The journalist was killed in Mexico Pacific coast state of Nayarit, the report said.
The year 2022 was among the deadliest ever for Mexican media workers, with 15 killed.
The journalist was killed in Mexico Pacific coast state of Nayarit, the report said.
According to the report in AP, the Mexican national newspaper La Jornada said that its staff reporter in the Pacific coast state of Nayarit has been found dead.
The body of journalist Luis Martín Sánchez Iñiguez was found on the outskirts of the state capital, Tepic, La Jornada reported.
Sánchez Iñiguez, 59, had been missing since Wednesday and an appeal had been made to find him, the Nayarit state prosecutors' office said on Saturday.
The journalist's wife reported him missing, along with a computer and his cellphone.
The office said later Saturday that relatives had identified Sánchez Iñiguez's body and that he had been dead for one or two days before the corpse was found.
"The body was found with signs of violence, and two handwritten signs were found on it," prosecutors said in a statement, but did not reveal what the messages said.
Handwritten signs are frequently left by drug cartels with the bodies of victims, but the office said the motive in the killing was still under investigation.
Sánchez Iñiguez was last seen in Xalisco, a Nayarit town that has long been linked to the smuggling of heroin and opium.
He would be at least the second journalist killed in Mexico this year.
In February, news photographer José Ramiro Araujo was stabbed and beaten to death in the northern Mexico border state of Baja California.
The year 2022 was among the deadliest ever for Mexican media workers, with 15 killed.
Just two days after Sánchez Iñiguez disappeared, another journalist was abducted in the same area. Jonathan Lora Ramírez was abducted on Friday by "armed, masked men who arrived at his home in Xalisco, forced open the door and took him away", state prosecutors said.
Lora Ramírez was found alive and in good condition Saturday, prosecutors said.
The prosecutors' office said a third media worker, identified as Osiris Maldonado, has been missing since July 3. Maldonado apparently worked in graphic design at La Jornada.
Prosecutors said they were investigating the possibility the abductions and killing were related to the journalists' profession.
The Committee to Protect Journalists said it "strongly condemns the killing of journalist Luis Martín Sánchez Iñíguez, correspondent of newspaper La Jornada, in the state of Nayarit, and calls on Mexican authorities to immediately and credibly investigate".
